Change ssh port

in /etc/ssh/sshd_config

change the port

Port 22



to anything you like

then restart sshd damon
dont forget to add that port in iptables
also only allow certain ip to connect to the servier via iptables

dont allow it to every one. its a security risk

file is seems like the given below will i remove the ->  #  
then i will change it to another port and i will configure iptables before doing this is this right ?

#Port 22
#Protocol 2,1
Protocol 2
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::

# HostKey for protocol version 1
#HostKey /etc/ssh/ssh_host_key
# HostKeys for protocol version 2
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key

# Lifetime and size of ephemeral version 1 server key
#KeyRegenerationInterval 1h
#ServerKeyBits 768

Select allOpen in new window

Remove #  and change to anything like

Port 222

but change the iptables rules first. and restart iptables


-A RH-Firewall-1-INPUT -s xx.xx.xx.xxx -p tcp -m tcp --dport 222 -j ACCEPT


upper rules will allow only that ip to allow your ssh

ok then how could i restart ssh service to activate new port
